无法将数据插入表
这是一个必须插入到我的数据库中的文件的示例。将文件以简单的形式上传到服务器。
{
“FileName”: “XXXX",
“Code”: “11112233",
“Contacts”: [
{
“rowId” => '',
“TicketId” => "xxxxxxxxxxxx",
“otherId” => "YYYYYYYYYYYYYYYYYYYYYYY",
“ClientId” => "wwwwwwwwwwwwwwwwwwwwwwwwwww",
“Name” => "MARCELLO",
“LName” => "MARCELLO",
“Phone” => "4315415151434",
“ADDRESS” => "hhhhhvofvofvvv",
“Mail” => "dfwfwf@fwes.fd"
},
{
“rowId” => '',
“TicketId” => "xxxxxxxxxxxx",
“otherId” => "YYYYYYYYYYYYYYYYYYYYYYY",
“ClientId” => "wwwwwwwwwwwwwwwwwwwwwwwwwww",
“Name” => "MARCELLO",
“LName” => "MARCELLO",
“Phone” => "4315415151434",
“ADDRESS” => "hhhhhvofvofvvv",
“Mail” => "dfwfwf@fwes.fd"
}
]
}
在主页中，我包括用于连接数据库的脚本 我确定它可以正常工作，通常用于我网络工作的所有其他页面。
$host = "localhost";
$db_user = "xxxx";
$db_pw = "xxxxx";
$db_name = "xxxxx";
// connessione
try {
// stringa di connessione al DBMS
$connessione = new PDO("mysql:host=$host;dbname=$db_name", $db_user, $db_pw);
// impostazione dell'attributo per il report degli errori
$connessione->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e)
{
// notifica in caso di errore nel tentativo di connessione
echo "Errore:" .$e->getMessage();
die();
}
这是我上传页面代码的一部分，对我没有帮助：
$file = file_get_contents($filejson);
if(!function_exists('json_decode')) die('Il server non ha tale funzione');
$result = json_decode($file, true);
foreach ($result as $row){
$sql = "INSERT INTO ibl_Anag (TicketId,otherId,ClientId,Name,LName,MobPhone,Phone,address,mail)
VALUES ('".$row["TicketId"]."'
,'".$row["otherId"]."'
,'".$row["ClientId"]."'
,'".$row["Name"]."'
,'".$row["LName"]."'
,'".$row["Phone"]."'
,'".$row["MainPhone"]."'
,'".$row["address"]."'
,'".$row["mail"]."' )";
$stmt=$connessione->prepare($sql);
$stmt->execute();
if(!$stmt){Echo "la insert non ha funzionato";}
}
我没有从代码中得到错误，但是数据没有插入到mysql表中。可能我在脚本的逻辑上做错了，但不知道在哪里。谁能帮帮我吗。谢谢。

您需要考虑以下因素：
?，准备一次该语句，将值绑定到参数并多次执行该语句。 JSON无效（如问题中所述）。使用有效的JSON并从此"Contacts"中读取JSON数组以执行语句。另外，您的"MainPhone"中没有JSON，而"address"是"ADDRESS"。您可以尝试以下代码：
<?php
# Connection
$host = "localhost";
$db_user = "xxxx";
$db_pw = "xxxxx";
$db_name = "xxxxx";
try {
$connessione = new PDO("mysql:host=$host;dbname=$db_name", $db_user, $db_pw);
$connessione->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
echo "Errore:" .$e->getMessage();
die();
}
# Data
$file = file_get_contents($filejson);
if (!function_exists('json_decode')) {
die('Il server non ha tale funzione');
}
$result = json_decode($file, true);
# Prepare and execute statement
try {
$sql =
"INSERT INTO ibl_Anag (TicketId,otherId,ClientId,Name,LName,MobPhone,Phone,address,mail)
VALUES (?,?,?,?,?,?,?,?,?)";
$stmt = $connessione->prepare($sql);
foreach ($result["Contacts"] as $row) {
$ticketId = $row["TicketId"];
$otherId = $row["otherId"];
$clientId = $row["ClientId"];
$name = $row["Name"];
$lname = $row["LName"];
$mobPhone = $row["Phone"];
$phone = $row["Phone"];
$address = $row["ADDRESS"];
$mail = $row["mail"];
$stmt->BindParam(1, $ticketId);
$stmt->BindParam(2, $otherId);
$stmt->BindParam(3, $clientId);
$stmt->BindParam(4, $name);
$stmt->BindParam(5, $lname);
$stmt->BindParam(6, $mobPhone);
$stmt->BindParam(7, $phone);
$stmt->BindParam(8, $address);
$stmt->BindParam(9, $mail);
if (!$stmt->execute()) {
echo "la insert non ha funzionato";
}
}
} catch(PDOException $e) {
echo "Errore:" .$e->getMessage();
die();
}
?>
示例的有效JSON：
{
"FileName": "XXXX",
"Code": "11112233",
"Contacts": [
{
"rowId": "",
"TicketId": "xxxxxxxxxxxx",
"otherId": "YYYYYYYYYYYYYYYYYYYYYYY",
"ClientId": "wwwwwwwwwwwwwwwwwwwwwwwwwww",
"Name": "MARCELLO",
"LName": "MARCELLO",
"Phone": "4315415151434",
"ADDRESS": "hhhhhvofvofvvv",
"Mail": "dfwfwf@fwes.fd"
},
{
"rowId": "",
"TicketId": "xxxxxxxxxxxx",
"otherId": "YYYYYYYYYYYYYYYYYYYYYYY",
"ClientId": "wwwwwwwwwwwwwwwwwwwwwwwwwww",
"Name": "MARCELLO",
"LName": "MARCELLO",
"Phone": "4315415151434",
"ADDRESS": "hhhhhvofvofvvv",
"Mail": "dfwfwf@fwes.fd"
}
]
}

要正确使用准备好的语句，需要在执行语句之前在绑定变量的SQL语句中分配占位符。这样做的好处是，您只需在循环外创建一次prepared statement，然后只需更改命名变量的赋值即可在循环中执行多次。以下代码未经测试，但应将您引向最终目标。
下面的代码正在使用mySQLi-如果使用PDO，则可以使用类似的方法，除了在将变量分配给bindParam等之前，变量应该存在，即使是空变量也是如此
$sql='insert into ibl_anag
( `ticketid`,`otherid`,`clientid`,`name`,`lname`,`mobphone`,`phone`,`address`,`mail` )
values
(?,?,?,?,?,?,?,?,?)';
$stmt=$connessione->prepare( $sql );
if( $stmt ){
/*
assumed that fields named as ID are integers,
other firlds are strings
*/
$stmt->bind_params( 'iiissssss', $tid,$oid,$cid,$name,$lname,$mob,$phone,$addr,$email );
$json = json_decode( file_get_contents( $filejson ) );
foreach( $json as $obj ){
$tid=$obj->TicketId;
$oid=$obj->otherId;
$cid=$obj->ClientId;
$name=$obj->Name;
$lname=$obj->LName;
$mob=$obj->Phone;
$phone=$obj->MainPhone;
$addr=$obj->address;
$email=$obj->mail;
$stmt->execute();
}
$stmt->close();
}
对于PDO，您可以尝试以下操作：
$sql='insert into ibl_anag
( `ticketid`,`otherid`,`clientid`,`name`,`lname`,`mobphone`,`phone`,`address`,`mail` )
values
(:tid,:oid,:cid,:name,:lname,:mob,:phone,:addr,:email)';
$stmt=$connessione->prepare( $sql );
if( $stmt ){
$json = json_decode( file_get_contents( $filejson ) );
foreach( $json as $obj ){
$stmt->execute(array(
':tid' => $obj->TicketId,
':oid' => $obj->otherId,
':cid' => $obj->ClientId,
':name' => $obj->Name,
':lname'=> $obj->LName,
':mob' => $obj->Phone,
':phone'=> $obj->MainPhone,
':addr' => $obj->address,
':email'=> $obj->mail
));
}
}
